2. Concrete degradation - Wikipedia

   en.wikipedia.org/wiki/Concrete_degradation

   The filling of cracks, fissures or voids in concrete for structural purposes (restoration of strength and load-bearing capability), or non-structural reasons (flexible repairs where further movement is expected, or alternately to resist water and gas permeation) typically involves the injection of low viscosity resins or grouts based on epoxy ...

3. Self-healing concrete - Wikipedia

   en.wikipedia.org/wiki/Self-healing_concrete

   Autogenous self-healing crack. Self-healing concrete is characterized as the capability of concrete to fix its cracks on its own autogenously or autonomously. It not only seals the cracks but also partially or entirely recovers the mechanical properties of the structural elements. This kind of concrete is also known as self-repairing concrete.

4. Polymer concrete - Wikipedia

   en.wikipedia.org/wiki/Polymer_concrete

   Polymer concrete is a type of concrete that uses a polymer to replace lime-type cements as a binder. One specific type is epoxy granite , where the polymer used is exclusively epoxy . In some cases the polymer is used in addition to portland cement to form Polymer Cement Concrete (PCC) or Polymer Modified Concrete (PMC). [ 1 ]

5. Alkali–silica reaction - Wikipedia

   en.wikipedia.org/wiki/Alkali–silica_reaction

   Typical crack pattern of the alkali-silica reaction (ASR). The gel exudations through the concrete cracks have a characteristic yellow color and a high pH. The fatty aspect of the exudations imbibing the concrete porosity along the cracks is also a distinctive feature of ASR. The alkali-silica reaction as a chemical cycle process

6. Filler (materials) - Wikipedia

   en.wikipedia.org/wiki/Filler_(materials)

   Filler can have a negative or positive effect on fatigue resistance depending on the filler type and shape. In general fillers create small discontinuities in the matrix. This can contribute to crack initiation point. If the filler is brittle fatigue resistance will be low, whereas if the filler is very ductile the composite will be fatigue ...

7. Polished concrete - Wikipedia

   en.wikipedia.org/wiki/Polished_concrete

   The mix design of the concrete should be 3500 psi or higher. The concrete should be poured full depth to take advantage of the concrete's full structural strength, and also help to prevent cracks. The concrete should always be professionally finished with power trowels and cured with water for seven days. Polishing should not begin until the ...

9. High-performance fiber-reinforced cementitious composites

   en.wikipedia.org/wiki/High-performance_fiber...

   More notable, however, is the extremely high ultimate strain value of 5.6% when compared to most FRC's ultimate strain values ranging in the few hundredths of a percent. The first crack stress and first crack strain values are significantly low compared to normal concrete, both the result of the multiple crack phenomenon associated with HPFRCCs.
